Thanks for the speedy and detailed response. I was thinking of layering the images in the fashion you mentioned but i like the idea of not doing much post editing. I guess that is the best bet though. I just got this camera for Xmas so i am still learning all the basic functions of the camera. This is my first SLR camera so please go easy on me if i sound like an idiot.
I am looking into getting a different lense for it. I have the canon eos rebel XT. I want a lense that can take decent macros of the corals in the back of the tank but also want to be able to get decent full view shots and partial landscape pics. I was looking at the the 100mm macro lense that cannon makes for this body. Would i be better off getting a lense that is say 18-200mm so i can use it for both macros and other stuff. I am aware a specific macro lense would be best but for me i dont need a specific lense for each specific application. Id rather have a decent lense that i can use for multiple applications.
